Sonoff for button (pulse) and not switch

I bought many Sonoff and some Sonoff PRO. My light system uses switching relay which work with a (just a pulse) button. How can I do? Somebody can help me? 

There is an easy way to  enter in the management software and set pulse and not switch?

Some advice?

Thank you

I wait for a On /off pulse switch

If you are good  with DIY skills you have an option. You can search YouTube for modification to the Sonoff switches. Search for  "Using Sonoff SV as a Dry Contact (no voltage) Relay" on google or YouTube. 


Normally Sonoff switches connect and disconnect live input from mains power to the output terminal. The neutral is permanently connected. The modification I am talking about disconnects the out put terminal from the input and bridges them in such a way that they turn into simple on off or momentary switches connecting the 2 output terminals which are totally isolated from the rest of the circuit. You could switch any voltage from 5 to 250 volts. 

Thanks a lot. I have seen that video but I dislike to make an hardware modification.

I misunderstood the meaning of switch, I thought was possible to configure both as switch and pulse switch . I was terrible wrong. May I suggest to use another software like Smart life. There is an option on other (altro) where is a function door (porta): I would like to test it later.

Anyway up to date the only useful suggestion is your. 

There are other non Sonoff remote controls  - like car remote - that can work for you. These run from mains power 70V to 250V. And have changeover relay with 3 terminals. These 3 terminals are completely isolated from the mains and controller circuits. Available as set of  1, 2 or 4 receivers with equal number of transmitters.


 They also have a jumper setting that can set the behaviour of the relay to toggle, latch or momentary.  The contacts  are rated 250 V 10A on NO (switched) terminal and 7A on NC terminal. 

thanks, that's very kind of you.

Could you tell me where to find them, please ??

regards

I got mine from AliExpress. I bought one set that consisted of 4 mains powered  receivers each with a completely isolated changeover relay and  4 (four) pre-programmed 4 button remotes.  I have used them at a distance of 50+ meters around corners and bends in solid brick & mortar building.

The shipping charges are shown jacked up and vary from country to country as cheaper but reliable options have been blocked due to lockdown in many countries.
